Maximum Accommodation Capacity Decomposition of Distributed Renewable Power Generation Considering Multi-Level Distribution Network
摘要
Abstract
With the integration of distributed renewable energy sources(RES)into various levels of distribution networks characterized by their"numerous and widely distributed"nature,the power grid exhibits a multi-level access and integrated consumption pattern for renewable energy.To facilitate the full consumption and efficient utilization of renewable energy,a model for calculating the maximum consumption capacity of RES in multi-level distribution networks is proposed.This approach transforms the complex task of estimating the maximum RES consumption capacity in the entire system into sub-problems focused on individual distribution network levels,thereby enabling precise measurements of the maximum RES consumption space at each level.Firstly,with the objective of maximizing the RES penetration within the multi-level distribution network,a consumption space calculation model is established based on the Distflow power flow model.Secondly,to address the issues of non-convexity and low solution efficiency inherent in the model,a second-order cone relaxation technique is applied to transform the model into a mixed-integer second-order cone programming(MISOCP)model.Subsequently,the alternating direction method of multipliers(ADMM)is employed to decompose the overall RES consumption space estimation problem into sub-problems focused on individual distribution network levels,effectively transforming the consumption space model into a decomposed calculation model for the maximum RES consumption capacity across the multi-level distribution network.Finally,the effectiveness of this methodology is demonstrated through simulations on the IEEE 6,7,9,10,12,and 15 test systems.关键词
